Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters, 10 - Synthesis and characterization of alpha,omega-dihydroxyoligo(alkylene maleate)s
(Wiley-VCH Verlag Gmbh, Weinheim, 1998)
alpha,omega-Dihydroxyoligo(alkylene maleate)s with molecular weights ranging from 1500 to 4000 were prepared by polycondensation, in 1-methyl-2-pyrrolidone at 105 degrees C, of potassium maleate and 1,4-dibromobutane, ...
The thermogravimetric analysis of some polysiloxanes
(Elsevier Ltd., 1998)
Thermogravimetric (TG) and differential thermogravimetric analyses (DTG) of some homo- and copolymers of dimethylsiloxane have been performed. The effect of the presence of hydrido-substituents and/or vinyl end-groups on ...
Modeling of drawing thin glass sheet from a preform
(Serbian Chemical Society, Belgrade, 1998)
A one-dimensional model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of ...
Reactivity of beta-aroylacrylic acids with diazodiphenylmethane
(Serbian Chemical Society, Belgrade, 1998)
The rate constants for 10 trans-substituted beta-aroylacrylic acids in their reaction with diazodiphenylmethane (DDM) were determined in ethanol at 30 degrees C. The intention was to study the transmission of electronic ...
Cubic equation of state models for the liquid excess heat capacity calculations. I. Mixing rules
(Serbian Chemical Society, Belgrade, 1998)
Binary liquid excess heat capacities, c(p)(E), were calculated by the PRSV EOS coupled with the van der Waals one fluid (vdW), the modified van der Waals one fluid (Schwartzentruber-Renon)(SR) and the Orbey-Sandler ...
The potential of piezoelectric sensors for characterization of activated carbon cloth applied in adsorption of phenols from air
(Amer Chemical Soc, Washington, 1998)
Characterisation of activated carbon cloth (ACC) applied for phenols adsorption from the air was performed by a pair of coated piezoelectric quartz crystals as sensors. ACC cloth was impregnated with specific organic ...
Sulphatization of manganese slime from zinc electrolysis with ferrosulphate
(Wiley, Hoboken, 1998)
The kinetics and mechanism of the sulphatization of manganese slime from the zinc electrolysis with Fe(ll) sulphate was studied. The priority of chemical reactions was determined on the basis of the results of thermodynamic ...
Synthesis and characterization of a new chiral polyurea-based catalyst
(John Wiley & Sons Inc, New York, 1996)
A series of chiral poly(urea)s was synthesized by solution polyaddition. The polymers are characterized by NMR, FTIR, DSC, viscosimetry, and microanalysis. After deposition of the rhodium, the insoluble chiral polymers ...
The sorption characteristics of epoxy coatings electrodeposited on steel during exposure to different corrosive agents
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
Organic protective coatings on steel were formed by cathodic electrodeposition of an epoxy resin modified by an amine and isocyanate using a constant voltage method (resin concentration 10% wt, temperature 26 degrees C, ...
Extraction of cesium from an alkaline leaching solution of spent catalysts using an ion-exchange column
(Marcel Dekker Inc, New York, 1996)
The selective extraction of cesium from an alkaline leaching solution of spent catalysts using phenolic resins was studied. The resins were synthesized by alkaline polycondensation of formaldehyde by phenol, resorcinol, ...
